[0002] The welding process requires a nut ejection test to verify weld strength. Currently, commonly used welding strength testing machines include a housing, electrical control box, test platform, hydraulic cylinder, and control buttons; this equipment is fully automated. However, welding strength testing machines are relatively expensive. Utility Model Content

[0003] In view of this, the present invention aims to propose a new type of welding nut ejection testing machine, which is suitable for ejecting welding bolts on plate-shaped workpieces, improving the operational safety of the testing machine, and reducing the production cost of the testing machine.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A novel welding nut ejection testing machine includes a housing, a power distribution box, a test platform, a hydraulic cylinder, and control buttons. It also includes a portal frame, an upper ejection assembly, a lower ejection assembly, and an adjustable base. The test platform is located inside the housing, and the portal frame is mounted on the test platform. A hydraulic cylinder is mounted on the crossbeam of the portal frame, and an adjustable base is located on the test platform below the portal frame. The hydraulic cylinder is connected to the upper ejection assembly, and the lower ejection assembly is located below the upper ejection assembly, connected to the adjustable base. The control buttons are connected to the power distribution box, which provides power to the testing machine.

[0006] The upper ejection assembly includes an upper guide rod, a pressure sensor, and a pressure block. The push rod of the hydraulic cylinder is connected to the upper guide rod, which is arranged vertically. A pressure sensor is installed at the end of the upper guide rod, and the pressure sensor is connected to the pressure block. The lower ejection assembly includes a lower guide rod and a pad. The lower guide rod is arranged vertically, and the top of the lower guide rod is connected to the pad. The pad is positioned directly below the pressure block.

[0007] The adjustable base includes a handwheel, a lifting component, and a lifting platform. The lifting component includes a worm gear and a worm that cooperate with each other. The worm gear is connected to the handwheel, the worm is vertically arranged, and its top end is connected to the lifting platform. The lifting platform is connected to the pad block.

[0008] Furthermore, a protective cover is provided on the pressure block. The protective cover is a downwardly protruding arc-shaped sidewall, which is provided along the front edge of the pressure block.

[0009] Furthermore, the housing is provided with double-door panels.

[0010] Furthermore, a base is provided below the experimental platform, and the power distribution box is mounted on the base.

Detailed Implementation

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] like Figure 1 As shown, a novel welding nut ejection testing machine includes a housing 1, a power distribution box 15, a test platform 7, a hydraulic cylinder 2, and control buttons. It also includes a portal frame 3, an upper ejection assembly, a lower ejection assembly, and an adjustable base 6. The test platform 7 is located inside the housing 1, and the portal frame 3 is mounted on the test platform 7. The hydraulic cylinder 2 is mounted on the crossbeam of the portal frame 3, and the adjustable base 6 is mounted on the test platform 7 below the portal frame 3. The hydraulic cylinder 2 is connected to the upper ejection assembly, and the lower ejection assembly is located below the upper ejection assembly. The lower ejection assembly is connected to the adjustable base 6. The control buttons are connected to the power distribution box 15, which provides power to the testing machine.

[0024] like Figure 1 and Figure 3 As shown, the upper ejection assembly includes an upper guide rod 9, a pressure sensor 10, and a pressure block 11. The push rod of the hydraulic cylinder 2 is connected to the upper guide rod 9, which is arranged vertically. The pressure sensor 10 is installed at the end of the upper guide rod 9 and is connected to the pressure block 11. The lower ejection assembly includes a lower guide rod 13 and a pad 12. The lower guide rod 13 is arranged vertically, and the top of the lower guide rod 13 is connected to the pad 12. The pad 12 is positioned directly below the pressure block 11.

[0025] like Figure 2 As shown, the adjustable base 6 includes a handwheel 20, a lifting component, and a lifting platform 22. The lifting component includes a worm gear and a worm that cooperate with each other. The worm gear is connected to the handwheel 20, and the worm 21 is vertically arranged with its top end connected to the lifting platform 22. The lifting platform 22 is connected to the pad block 12.

[0026] The experimental steps of this novel welding nut ejection test machine are as follows: Figure 2 and Figure 3As shown, firstly, the plate-shaped workpiece 17 is placed on the pad 12, between the pad 12 and the pressure block 11. The upper end of the welding bolt 18 is placed against the pressure block 11, and the lower end of the welding bolt 18 is placed against the pad 12. Then, the handwheel 20 is manually turned to raise the height of the lifting platform 22 through the cooperation of the worm gear and worm, pre-tightening the plate-shaped workpiece 17 between the pad 12 and the pressure block 11. Afterwards, the hydraulic cylinder 2 is started by pressing the control button. The push rod of the hydraulic cylinder 2 drives the upper guide rod 9 to press down, driving the pressure sensor 10 and the pressure block 11 to press down, thus conducting the welding nut ejection test. During the pressing test, the pressure data is collected by the pressure sensor 10. This utility model allows for manual adjustment of the lifting platform 22 via the adjustable base 6, enabling pre-tightening of the plate-shaped workpiece. After pre-tightening, the workpiece is pre-fixed. Once the manual operation is completed, the manual hand is removed before the ejection test, making it safer. Furthermore, the overall structure of the testing machine is simple and the production cost is low.

[0027] As one of the preferred embodiments of this invention, the pressure sensor 10 is a spoke-type pressure sensor with a pressure range of 0-5T.

[0028] like Figure 3 As shown, a protective cover 16 is provided on the pressure block 11. The protective cover 16 is a downwardly convex arc-shaped sidewall, which is provided along the front edge of the pressure block 11. The arc-shaped sidewall surrounds the welding bolt to prevent bolt spatter and improve safety.

[0029] like Figure 1 As shown, the housing 1 is equipped with a double-leaf door panel 14. A base 8 is located below the experimental platform 7, and the power distribution box 15 is mounted on the base 8. The structure is compact, reducing the floor space required.

[0030] like Figure 1 As shown, the control buttons include a start button 4 and a stop button 5. The pressure sensor 10 is connected to a pressure display screen 23, which is located on the upper part of the housing 1. The pressure sensor 10 is connected to the pressure display screen 23 to display the current pressure, and experimental data is recorded based on the current pressure displayed on the pressure display screen 23. Furthermore, the manual rotation of the handwheel 20 to raise the pressure can be stopped based on the current pressure displayed on the pressure display screen 23, making the adjustment operation convenient.
